Resumo:
Blockchain is the technology that allows the transaction of money between parties in
a peer-to-peer manner without the need of a trusted intermediary such as banks. This
technology is known for its attractive characteristics: (i) the data integrity, and (ii) security.
To take advantage of such characteristics, some blockchain networks are not focused
on their cryptocurrency. One of those networks is the Ethereum network, which is a
platform for smart contracts. Smart contracts are applications that represent an agreement
between parties in a decentralized manner. These algorithms are deployed on the system
and can be globally accessed. They are executed without the possibility of censorship,
fraud, or external third party intervention. One of their possible applications is the smart
property concept that is transacting property on the blockchain. This can be applied on
the property rental context and the raising use of services such as AirBnB due to its
financial attractiveness to its users, there is a need to develop a system capable of solving
the security issues while providing comfort. This work will presents the development of a
project that studies the viability of applying the concept of smart property. A reservation
platform was developed where the user makes one reservation and, when approved, a
smart contract is deployed to the Ethereum platform. To access the property, the user
uses the application developed for Android which transfer the credentials using a data
through sound protocol. The lock verifies these credentials accessing the smart contract
and activates the lock’s circuit allowing access to the property. To examine the viability of
this project, tests were performed with supposed users of this system who also answered a
survey. After the analysis of this survey, the project proved to be viable, more attractive
than the traditional standard, functional, and provided comfort.
